A researcher wishes to study the effect of cognitive behavior therapy on young people diagnosed with depression. Consider and discuss the following questions as you respond:

  • Would you recommend using a z test, a t test, or an ANOVA for the analysis? Explain your answer.
  • What would your choice of test depend on? For the test you select, explain your design and your comparison groups.
  • Would the hypothesis be directional or nondirectional?
  • Would the test be one or two tailed?
  • How would the null and alternative hypotheses be worded?
